Number of Epochs

Maximum number of complete passes through the training data.

An epoch is one complete pass through all sampled training patches. This field sits in the Training Budget group, accepts values from 10 to 500 (step 10), and is the main knob the presets change.

Preset budgets

The epoch count set by each preset depends on which branch trains:

• Fast: 50 (N2V branch) / 50 (StructN2V branch)

• Balanced: 200 (N2V branch) / 100 (StructN2V branch)

• High Quality: 400 (N2V branch) / 200 (StructN2V branch)

Fewer epochs train faster but may not fully converge; more epochs give a better chance of convergence at the cost of runtime.

Early Stopping

When enabled, training stops automatically if the validation loss does not improve for several epochs (set by the patience value). This means you can set a high epoch count safely — training ends early once it converges.

Recommendations

• Use the Balanced preset for most work

• Switch to High Quality for final results, or Fast for quick tests

• Leave early stopping on so the epoch count acts as a ceiling, not a fixed runtime
